Enderman shouldn't be able to spawn back

If you killed many enderman in a around a place (for example spawn), they should not spawn back near where they were killed (I think about a 50 block radius around death) . This feature should also only work in the overworld. One main problem I have in every server is that the enderman won't stop griefing my base and the ground. If you have played minecraft for a long of time, you'll notice how the ground and your base is constantly getting griefed by enderman, which really ruins the view. This griefing is hard to remove because turning of mob griefing disables all mob griefing which I don't want, so I think this is a perfect solution.
